FolderRisk: Safe
Low C:\Users\<utilisateur>\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low
Internet cache for low-integrity processes (Internet Explorer Protected Mode, legacy web components); contents can be cleared.
What it’s for
Low-integrity processes such as Internet Explorer in Protected Mode cannot write to the normal profile cache. Windows gives them this subfolder of Temporary Internet Files instead, the same way LocalLow serves application data.
What it contains
- Cached copies of pages, images and scripts from legacy web components.
- Cache subfolders such as
Content.IE5, created on demand. - On a recent installation where Internet Explorer is not used, the folder is often empty or missing.
Risks and best practices
- It is a cache: you can delete the files and they are downloaded again when needed. Keep the folder itself and its first-level subfolders.
- Close browsers and applications that host a web control before cleaning.
- A large size here points to an application that still relies on these components. Find it rather than emptying the folder on a schedule.
